Description

iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. In versions 2.3.1.1 and below, an integer overflow vulnerability exists in icValidateStatus CIccProfile::CheckHeader() when user-controllable input is incorporated into profile data unsafely. Tampering with tag tables, offsets, or size fields can trigger parsing errors, memory corruption, or DoS, potentially enabling arbitrary Code Execution or bypassing application logic. This issue has been fixed in version 2.3.1.2.

• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
